The protojson.Unmarshal function can enter an infinite loop when unmarshaling certain forms of invalid JSON. This condition can occur when unmarshaling into a message which contains a google.protobuf.Any value, or when the UnmarshalOptions.DiscardUnknown option is set.
A flaw was found in Golang's protobuf module, where the unmarshal function can enter an infinite loop when processing certain invalid inputs. This issue occurs during unmarshaling into a message that includes a google.protobuf.Any or when the UnmarshalOptions.DiscardUnknown option is enabled. This flaw allows an attacker to craft malicious input tailored to trigger the identified flaw in the unmarshal function. By providing carefully constructed invalid inputs, they could potentially cause the function to enter an infinite loop, resulting in a denial of service condition or other unintended behaviors in the affected system.
Отчет
Within regulated environments, a combination of the following controls acts as a significant barrier to successfully exploiting a CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') vulnerability and therefore downgrades the severity of this particular CVE from Moderate to Low. The platform enforces hardening guidelines to ensure the most restrictive setting needed for operational requirements. Event logs are collected and processed for centralization, correlation, analysis, monitoring, reporting, alerting, and retention. This process ensures that audit logs are generated for specific events involving sensitive information, enabling capabilities like excessive CPU usage, long execution times, or processes consuming abnormal amounts of memory. Static code analysis and peer code review techniques are used to execute robust input validation and error-handling mechanisms to ensure all user inputs are thoroughly validated, preventing infinite loops caused by malformed or unexpected input, such as unbounded user input or unexpected null values that cause loops to never terminate. In the event of successful exploitation, process isolation limits the effect of an infinite loop to a single process rather than allowing it to consume all system resources.
